Question about Sennheiser HD 25 SP Consumer Headphones

1 Answer

Cahnging plug Hi I got in touch with Sennheiser directly but they gave me no reply: I bought the HD-25 sp's to use with my ipod, so need to change the 1/4" jack to a mini-jack. There are 4 colours for the cables with no indication as to which is the ground and which is live. I've soldered it up just for now but I don't know if the phase is right:left- yellow and greyright- red and blueI've soldered the yellow and blue to the tip and ring and the others to the sleeve.Any ideas which are the right cables?Thanks,Ed Devane

    If anyone has this problem all they need do is open their eyes and see that the cable is detachable from the headphones themselves, and Sennheiser sell  replacements with a minijack plug. 27 euro, and 3 metres long, not exactly ideal...

The standard HD25SP cable's 1/4" jack screws over the mini-jack. There's no reason for you to do any soldering. If you have a few inches of cord left from where you cut the plug off you may want to re-splice the cable back together to their corresponding colours. Then unscrew the 1/4" ******** to reveal the mini-jack.

Sound in one headphone keeps going off and on, moving the wire around can fix it temporarily but is very annoying

You have a break in the cable. You don't say in what area it's in, so I will have to give you 3 ways of clearing the fault.
1: Break in, near or around the plug. The best solution is to cut off the plug making certain the break area goes with it. You can then fit a new 3.5mm plug. If you need advice on how to do this let me know.
2. Break halfway to 2-thirds along the cable. Again cut the cable to a point clear of the break, again fit a new plug. To extend it you can purchase an extension headphone cable from any hi-fi shop.
3. Break to close to headset. In which case you will need to replace the entire lead. To do this you need to open up the headphones. Access is obtained by removing the pad(s) and any foam. You might need to force the foam off. You can glue it back on afterwards. You should then see screws to open it.
Fitting new plugs or attaching the wire inside will require the use of a small soldering iron.

have you tried a factory reset (in itunes, while your ipod is plugged in, click on the ipod touch icon to the left, then go to general, and go to "reset ipod to factory settings" or something similar)...this will only erase what is on your won't affect your itunes. also, if you already tried reseting it and still not could get the 2.0 firmware's about $10 dollars to upgrade to that though (i'm not a fan of apple...especially not now) you can get the upgrade directly from the apple website here try those solutions. also make sure you have the correct drivers installed..which would be ..and if those don't work, i would call apple and talk to them about that issue..if it is still under warranty, you should be fine to have it replaced (or if you bought it somewhat recently) and if'll have to sharpen your voice to a almost threatening tone and apple will most likely give in and either replace it or give you money.. ((i called them when i got an ipod video 30 gig, and 1 week later they released the 60 gig for the same price as the i called them and yelled at them alittle bit...they gave me $50))....i hope this has helped....oh and do you have a mac or windows? is it 1st generation ipod touch or 2nd generation (very thin is 2nd generation)? also make sure the drivers are up to date (if your computer is connected to the internet, open itunes and plug in your ipod, it should tell you if you need new drivers...if not, you're good)
